After a brief discussion, it was decided that Didi would remain human for the time being, albeit a human with a working dog cock and balls positioned above her pussy. They reasoned that since it was Jennifer's request, it wouldn't make sense if she had to wait months to fuck Ty, which was one of the main points of her request. The 3 of them headed over to the livingroom, where Didi sat down on the couch, and both Ty and Jennifer sat on the floor.
"Are we all good with what is about to happen? Ty said, asking for a final confirmation from the others.
"All ready, I hope you become a cute bitch Ty" said Didi.
"Just remember that he is going to be MY bitch first, Didi. You can still fuck him, but only after I impregnat him, or rather, since Ty will soon be a girl, her " said Jennifer.
"Oh yeah, I have to find a cute new name for you. As you soon to be owner, it is my responsibility to name my pets. Jennifer will stay Jennifer, but Ty will be uhhhh... how about... Stella?"
"What? Why Stella? That isn't even close to Ty. Also, why can't I pick my own name?" asked Ty confused, but also somewhat annoyed that he wasn't going to be the one to rename himself.
"Because I am the owner. Dogs don't name themselves. Also I couldn't think of a girls name similar to Ty that I liked. So I picked Stella. It even has a 'T' in it" answered Didi.
"I'm fine with it, Stella is a great name" chimmed in Jennifer.
"Yes!!!" Cheered Didi. "There, 2-1 for Stella. Now lets get this going. Just thinking about it is already turning me on."
"Fine" Stella said, reluctantly accepting her new name. It was not like she hated it anyways. Honestly she also really liked the name, but it just felt a bit off that she basically had no say in deciding it. However, it wasn't something she needed to get too depressed about either. "I guess for the time being I can live with being called Stella. At least it isn't something degrading like 'Spot' or 'Doggy'. Anyways, time to start the changes."
As Stella said this, everyone was already beginning to change. First, Didi immediatly uncrossed her legs, as her new equipment started to grow. Her new balls first, growing fairly larger than she expected, each just under the size of an orange, quickly followed by her cock. Her cock on the other hand, was not as big as she thought it would be. Only getting about 5 inches in length before stopping. However, this was just her misunderstanding. What she saw was only her sheath. The full length of her erect cock would be over a foot long.
A similar change happened to Jennifer. Jennifer, who had been sitting, just watched as her own cock and balls appeared. However, unlike Didi, her's was fully erect, splitting her 3 rows of tits, finally stopping with her gland resting in her top row's cleavage. Her tits pulling her cock close to her body, preventing it from dropping, or pointing away from her body. Every slight movement made her tits rub her cock, basically tittyfucking her full shaft. Her balls, also of a similar, but just a tad bigger size to Didi, started rapidly preparing sperm for her building orgasm.
Stella on the other hand, felt her entire body chamge. First her body repositioned itself to mimic a dog's sitting crouch, with her hands on the floor in front of her. Her hands and feet quickly became paws, covered in black fur, which spread up her legs and arms until it reached her thigh and shoulders. Her ass was next as it ballooned out, taking a similar shape to Jennifer's. This caused Stella to stand up, but now restricted to only standing on all 4s. However, this actually felt very comfortable to her. She looked behind her noting that it also made her ass look amazing, a thought which felt very odd for her. Stella never had thoughts like this when she was Ty. But she admitted to herself that she was enjoying having a nice ass. And looking over at Jennifer, it seemed that both were in agreement, given her full erection.
Stella also noticed that while she was looking over at Jennifer, her cock and balls absorbed into her body, and that a new opening had appeared. An opening that was getting wetter and wetter the longer she stared at Jennifer's gorgeous cock. While still in her trance, Stella had grew more fur, now covering most of her body, except for her face and underside.
Stella felt her chest tighten, as 6 more nipples appeared in 2 rows along her torso. Her waist also pulled in a bit, giving her what would be a very sexy figure. All 8 of her nipples started to push out, each becomming around an inch long, now technically teats, with her new breasts building up behind them. All 8 breasts were becomming quite large, ending at what she though was around a D-cup, and on top of that, all of them were full of milk.
The weight of her new boobs was something she knew she would need to get use to. Every slight movement made all of the jiggle about somewhat painfully too. Not wanting to spend the next few days in constant pain, Stella made it so that both her's and Jennifer's boobs would not be able to cause them harm, nor be in their way when running.
Finally Stella's last few changes finished up. Her tail and pointy ears covered themselves in black fur, as her now black nose pushed out from her face a bit, giving her a small mussel like Jennifer's. The last change was to her sense of smell though. Everything smelled so much stronger.
Especially 2 very particular smells. Both of which made her pussy soaked in anticipation.
"Now then" said Didi, "I'm going to go get some clothes on and go out to the pet store. Stella needs a collar, leash, and we need more dog food for you 2. And before you just make them Stella, I am doing this to give you some private time with Jennifer. Now that you are her bitch, her scent is clearly making you very horny. So don't let me interrupt". And with that, she dot up and walked out of the room, well sorta walked, but more closer to waddled, since her massive balls caused her legs to spread out quite a bit.
Now that they were alone, Jennifer, who was trying her best to not just immediately pounce on her bitch, looked over at Stella.
"What are you waiting for? Get that massive dick over here and fuck me. My pussy is aching for it."
Jennifer leapt up and mounted Stella. Both dog-girls now panting in extacy. Stella now felt that Jennifer's request for her to start a new new role as her bitch was the best idea she has ever heard. That nothing compared to the pleasure she felt as her mate's knot slid into her, sealing them together as Jennifer came, filling her womb to the max.
